Agree with twice a week and pluplu, these girl's looks and health are their only assets, and they are not forced to open the door and take a customer they do not like the looks of.
While I would not say I am a totally buff young man, I do keep myself fit and clean and have been to many places where a couple of polite knocks on the door bearing a "welcome" sign got me zip. Nada. Zero. Obviously the provider was watching me on the camera and decided I was not what she wanted to service. Perhaps GDS, I don't know.
Assuming a methadone clinic client did wander into the building with a hankering to do the deed, you have to assume the girl would not open the door, and would exercise her self-preservation instincts so she could live to see another customer more like anon-bear, whom I will assume he is clean, healthy, polite, and not a methadone clinic client.
If the provider did open the door to a methadone clinic as her client, Then she will probably be so messed up and unattractive that she would not be promoting herself on 141
. I am sure in some low end neighborhoods there are low end providers who do not advertise here, for example the punk mamasan who would sit in front of the building down the street from KP promoting a room full of low end Thai providers who would take on all commers for something like HKD 200, but they are not on this board.
Nothing to be worried about, in my view, if the girl is well kept it means she looks after herself and would be selective regarding clients.
one more hot chick for me to sample.
Keep on mongering
